TARGET

Turn off the light when not in use, Keep the future bright. The electric bill won't give you a fright if you remember to turn off the light. Like Money saved is Money earned, Power Saved is Power Generated.

Boost Charging


Boost Charging:

·         Boost charger is used to charge the battery from zero current to full current. This means the charger supplies, high current to the battery. Example now we need to charge a 12 V 100AH battery means with 200 Amps FLA charger means, the charger delivers maximum allowable current to the battery, hence the battery charges fastly.
·         Charging rate is high, typically full load capacity of the charger,
·         During emergency when A. C. supply fails, the battery shall meet the DC Load. Battery will be discharged after catering the load and it will require boost charging to charge the battery immediately when the battery working on high load requirement.
·         The output voltage is high, since the battery draw high amount of current from the charger.
·         Boost charger ensures that while boost charging if AC supply fails there shall not be any break in DC supply to load. Since this is a No Break Power Supply System.
·         It does not require being in online continuously.
